Animating with Space to Time

The two kinds of in-between commands are good for auto-animating straight lines, curved lines, and even circles—but what if we want a not-quite-so-generic motion? Director provides another technique, called Space to Time. With Space to Time, you place all the necessary sprites in a single Score frame, arranging them in the form of the action (it's kind of like a multiple-exposure photograph). Once you're satisfied with the flow of the sequence, a single command converts the arrangement into a segment suitable for playback.

Let's try this technique by making our Marble element seem to bounce. (Yes, bounce again, but this time let's see if we can make it look more realistic—did we mention that the marble is made of rubber?) We'll start by clearing the decks.
